Lifting usually starts with the prep. This course gives you the landmarks for a clean, safe prep, with a hand file or an e-file.

Lifting can have many causes. Here are the two most common, and the course that addresses each one.
Lifting often comes from the prep: a nail surface that is not properly prepared, or cuticle left on the nail plate.
Lifting can also come from the build: product poorly distributed, too thick at the edges, or touching the skin.

Lifting can have many causes, most often the prep or the way the nail is built. Start with Nail Prep, then choose the course that matches your method: nail forms or dual forms.

Two safe removal methods and the explanations to avoid that soft-nail feeling. And it's free.
Your result
Two methods, the same result. Full Set teaches shapes with nail forms. Dual Form teaches shapes with dual forms, with far less filing. Choose the one that suits the way you like to work.
Breakage often comes from an apex in the wrong place or poorly dosed, or from poor force distribution in the stress zone.
Breakage often comes from poor dual form placement, the wrong type or size of dual form, or weight and product that are not well balanced.

Real reviews from Kittycia students, translated from French.
Exceptionally high-quality courses! Step-by-step learning: understanding the shapes, positioning the nail form, structuring your filing to gain speed and build muscle memory. Explanations of common mistakes and so much more. […] Thank you Kittycia for your work, your patience, your advice and your critiques during corrections, because it's always in a kind spirit with the goal of helping us improve.
A thousand thank-yous for your online course on coffin and ballerina shapes! It's really very well explained and detailed. I've done in-person courses elsewhere (even though they were very good!) but the attention to detail in yours helped me understand all my mistakes. It's technical but so logical. In terms of value for money, I recommend it at 200%!
I highly recommend! Kittycia is a meticulous trainer! Don't be afraid of the distance, quite the opposite! You really get the feeling of doing a tailor-made course. And on top of that, you learn at your own pace. Brilliant!
Excellent trainer. I was sceptical at first […] I've just finished the salon almond advanced course and I'm hungry to do all the rest. She explains every which way with such a gentle voice. Thank you so much Kittycia, I've regained confidence in myself and I'm ready to make a whole array of happy clients.
I only work with acrygel, as it was the only technique I saw during my base training in October 2020. I was a little nervous about taking a gel advanced course, but Alicia's explanations are so clear and detailed that the product barely matters: you just adapt! I had never managed to do a proper almond shape, and after the course I feel like I finally understand!
Second training… At the top, super well explained, and I love the comparisons at certain moments that really make me laugh. I'm going to rewatch it this evening.

When I started in 2009, I spent three years making mistakes I couldn't explain. In 2012, I finally understood that every one of them had a reason, and I started training others.
Since then, I've earned more than 60 certificates, including 2 Master, and more than 23,000 nail technicians have trained with me, online since 2020.
